You know what really gets under my skin? The way we build cities in this country makes absolutely no sense. I mean, we spread everything out as far as possible, force everyone to drive everywhere, then wonder why our energy bills are through the roof and the air quality stinks.
This became painfully obvious to me last year during a project in Phoenix. The city brought me in to look at energy performance across different neighborhoods, and honestly? The numbers were depressing as hell.
These newer suburban developments – massive houses spread across endless cul-de-sacs – were burning through three times more energy per person than the older neighborhoods closer to downtown. Three times! And it wasn’t because the houses themselves were built terribly (though plenty were), but because the whole setup was designed to waste as much energy as possible.
I spent weeks walking around different parts of Phoenix, trying to figure out why some areas felt decent while others were completely miserable. The neighborhoods that actually worked had a few things in common. Buildings that created shade for sidewalks instead of baking them. You could walk to a coffee shop or grocery store without risking your life crossing six lanes of traffic. They’d planted trees that could actually survive in the desert. The streets were laid out to catch those evening breezes instead of blocking them.
But the energy-hungry suburbs? Complete opposite. Streets wide enough to land a plane on, all soaking up heat like solar collectors. Buildings scattered around with nothing but asphalt between them. Nobody had thought for two seconds about how structures might work together to make outdoor spaces livable. It was like they’d designed these places specifically to make people miserable and broke from cooling costs.
What I was seeing was the difference between actually planning how a city works versus just throwing buildings around randomly and hoping for the best. When you plan things properly, you’re not just designing individual buildings. You’re thinking about how they relate to each other, how people move between them, how wind and water flow through the area, how you can share infrastructure efficiently. Everything connects.
Here’s what drives me crazy though – we actually know how to do this better. I’ve seen it work. The old pueblo settlements figured this out centuries ago. They clustered buildings together so they’d shade each other. Built courtyards that would capture cool night air and slowly release it during hot days. Integrated their water systems right into how the settlement was laid out. Had gardens and agriculture woven throughout the living areas. This wasn’t accidental, it was sophisticated engineering that created comfortable, sustainable communities in harsh desert conditions.
Modern American cities went completely the opposite direction. We separate everything like we’re afraid different functions might contaminate each other. Houses here, offices there, shopping way over there where you need a car to reach it. Single-family homes on individual lots surrounded by private yards that nobody uses half the year because it’s 115 degrees outside. Office buildings sealed off from everything around them, fighting the climate with massive air conditioning systems instead of working with it. It’s honestly impressive how systematically we’ve designed cities to waste energy and make people miserable.
The thing is, fixing this doesn’t require some revolutionary breakthrough technology. During that Phoenix project, I found a few neighborhoods trying different approaches. One development near Scottsdale had clustered their buildings to create shared shade. They’d used light-colored paving that didn’t absorb as much heat. Positioned structures to funnel those desert breezes through pedestrian areas. The result? You could actually spend time outside during spring and fall without feeling like you were being cooked. Individual buildings needed less cooling. People actually talked to their neighbours because they could hang out in common areas.
Another area I studied was this mixed-use redevelopment in central Phoenix. Instead of separating housing and retail like they’re toxic to each other, they’d mixed them together vertically and horizontally. People could walk to get coffee, grab dinner, pick up groceries without starting their car. Buildings were designed to shade each other and create these little microclimates that were actually pleasant. They’d consolidated parking and put solar panels over it, generating power for the whole development. The energy numbers were great, but what really struck me was how much more alive the place felt compared to typical suburban developments.

They’d also thought about water management, which is huge in the Southwest. Instead of treating rainwater like toxic waste that needs to be flushed away immediately, they’d designed collection and infiltration systems that helped cool buildings and outdoor spaces. Captured water fed plants selected for local conditions, creating green spaces that didn’t need constant irrigation. It was like watching a small ecosystem actually function instead of fighting itself.
I’ve become convinced this integrated approach is the only way cities in hot climates will survive long-term. You can’t solve urban sustainability one building at a time because the problems are built into the whole system. Individual structures, no matter how efficient, can’t overcome the fundamental waste of car-dependent sprawl and isolated mechanical systems fighting against local climate conditions.
Transportation integration is especially critical. In typical sprawl, every building needs its own parking, its own HVAC system, its own everything. But when you cluster compatible uses and design for walkability, you can share infrastructure efficiently. Parking structures serve multiple buildings. District cooling systems serve entire neighborhoods more efficiently than individual building systems. Transit becomes viable because you have enough density and mixed uses to support it.
The economics work too, which always surprises people. Yeah, up-front costs might be higher because integrated planning requires more coordination and design time. But operational costs drop dramatically. Shared infrastructure costs less to maintain. People save money when they don’t need to drive everywhere. More efficient building performance means lower utility bills. Higher density means city services cost less per resident. It’s not just better for the environment, it’s economically smarter.
I’ve been working with several Southwest cities on updating their development codes to allow this kind of integration. The biggest obstacle isn’t technical – it’s regulatory. Most zoning codes were written specifically to prevent integration. They separate uses and require setbacks and parking ratios that make shared infrastructure difficult or impossible. Changing these codes requires political will and public education, which is slow, frustrating work.
But things are changing. Younger planners and architects get these principles better than previous generations. Climate change is forcing cities to think seriously about resource efficiency whether they want to or not. And residents are getting fed up with car-dependent sprawl, especially as traffic gets worse and housing costs keep climbing.
The key is demonstration projects that show integrated approaches actually working. People need to see and experience well-designed mixed-use developments with comfortable outdoor spaces and genuine walkability.
Once you’ve walked to dinner on a pleasant evening without crossing four lanes of blazing asphalt and dodging traffic, it’s hard to accept traditional sprawl as inevitable.
My work has evolved from analyzing individual building performance to helping cities understand how building performance connects to urban systems. It’s messier because you’re dealing with multiple stakeholders and complex regulations, but the potential impact is much larger. When cities get this right, the benefits multiply across thousands of buildings and hundreds of thousands of residents.
The Southwest has a real opportunity to lead on this because our climate challenges are so obvious. We can’t pretend mild weather will cover up energy waste like cities in temperate regions. Our conditions force us to be smarter about how we build and arrange communities. But that advantage only helps if we actually use it to create better places to live instead of continuing to build the same sprawling mistakes we’ve been making for decades.
